One In Four Earthquakes Worldwide Come From Deep Within Earth
2013-12-12 08:16:04

April Flowers for redOrbit.com - Your Universe Online The long standing mystery of what drives a particular type of earthquake that occurs deep within the Earth and accounts for one in four quakes worldwide might have been solved by a team led by Stanford researchers. Their findings are published in an upcoming issue of Geophysical Research Letters. Originating farther inside the planet than shallow earthquakes, these temblors are known as intermediate-depth earthquakes. Shallow...

Japanese Earthquake And Tsunami

[ Watch the Video: What Is At Fault For The 2011 Fukushima Earthquake And Tsunami? ] redOrbit Staff & Wire Reports - Your Universe Online The magnitude 9.0 Tohoku-Oki earthquake that occurred off the Japanese coast in March 2011, triggering a tsunami and ultimately resulting in more than 15,000 deaths, was the result of the largest fault slip ever recorded, according to a trio of studies published Thursday in the journal Science. According to Jane J. Lee of National Geographic,...

Earthquake Prone Regions Could Benefit From Updated Warning System
2013-10-31 08:52:18

redOrbit Staff & Wire Reports - Your Universe Online Relocating some of the seismic stations in California and upgrading earthquake-detection technology could improve early warning systems throughout the state, according to new research appearing in the November edition of the the journal Seismological Research Letters. The effect would be particularly noticeable in regions that are poorly served by the current network, explained Serdar Kuyuk, assistant professor of civil...

Google Street View Tool Used To Record Earthquake Damage
2013-10-30 11:13:09

Seismological Society of America 2009 L'Aquila quake's destruction revealed through contrast of images A scientist from Cologne University has used Google's online street view scans to document the damage caused by the 2009 L'Aquila earthquake and suggests that the database would be a useful tool for surveying damage caused by future earthquakes. The findings are published in the November issue of the Seismological Research Letters. The magnitude 6.3 2009 L'Aquila earthquake in the...

New Study Reveals Quake-triggered Landslides Pose Significant Hazard For Seattle
2013-10-22 13:40:44

Seismological Society of America A new study suggests the next big quake on the Seattle fault may cause devastating damage from landslides, greater than previously thought and beyond the areas currently defined as prone to landslides. Published online Oct. 22 by the Bulletin of the Seismological Society of America (BSSA), the research offers a framework for simulating hundreds of earthquake scenarios for the Seattle area. "A major quake along the Seattle fault is among the worst case...

Powerful Earthquake Rocks Philippines On National Holiday
2013-10-15 06:59:43

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful 7.1-magnitude earthquake rocked the Philippines Tuesday morning, killing at least 85 people and injuring hundreds more. The temblor occurred on October 15 at about 8:12 a.m. (local time) and, according to Renato Solidum of the Philippine Institute of Volcanology and Seismology, it was centered about 32 miles underground near the small town of Carmen. However, a report by the US Geological Survey (USGS) said the quake...

The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to understand. Scientists use seismic waves - pulses of energy generated during earthquakes - to measure what is happening in the Earth's inner core, which at 6000 km beneath our feet is completely inaccessible. Problematically for researchers, the results of seismic measurements...

Seismology is the scientific study of earthquakes and the spread of elastic waves through the Earth or through other planet-like bodies. The field includes studies of earthquake effects, such as tsunamis in addition to diverse seismic sources such as tectonic, volcanic, oceanic, atmospheric, and artificial processes. A related field that utilizes geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is a seismogram. A...

The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...

The Seismometer is an instrument designed to measure the motions of the ground. This includes seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of these activities allow seismologists to map the interior of the Earth, and locate and measure the size of the different sources. There are also seismographs, which is sometimes used in place of the word seismometer. However, a seismograph is the older instrument in which the measuring and recording...
